Times are changing and spying has become a common phenomenon everywhere.
There have been increasing instances where even the governments have been found
to be spying on their citizens from time to time. This is one of the prime
reasons why the importance of Encryption has increased manifold. Encryption
tools are very important because they keep the data safe by encrypting it so
that even if someone accesses the data, they can’t get through the data unless
they know how to decrypt the data. These tools use algorithm schemes to encode
the data to prevent unauthorized access to the encrypted data.
Some of the popular Encryption Tools will be discussed in this article:-
TrueCrypt is open source encryption tool which can encrypt a partition in
the Windows environment (except Windows 8); it’s equipped for creating a
virtual encrypted disk in a file. Moreover, it has the capability to encrypt
the complete storage device. TrueCrypt can run on different operating systems
like Linux, Microsoft Windows and OSX. TrueCrypt stores the encryption keys in
the RAM of the computer.
OpenSSH is the short name for Open Secure Shell and is a free software suite
which is used to make your network connections secured. It uses the SSH
protocol to provide encrypted communication sessions in a computer network. It
was designed originally as an alternative to the Secure Shell Software
developed by SSH Communications Security. The tool was designed as a part of
the OpenBSD project.
It an open source encryption tool available on both UNIX and Windows
operating system. It is a free implementation of SSH (Secure Shell) and Telnet
for both Windows as well as UNIX. The beauty of this tool is that it supports
many network protocols like Telnet, SCP, rlogin, SSH and raw socket connection.
The word PuTTY has no specific meaning, however as in UNIX tradition, tty is a
terminal name.
OpenSSL is an open source encryption tool which implements the TLS and SSL
protocols. OpenSSL’s core library is written in the C programming language. The
fundamental cryptographic functions are implemented by it. OpenSSL versions are
available for operating systems like UNIX, Solaris, Linux and Mac OS X. The
project was undertaken in 1988 with the objective of inventing free encryption
tools for the programs being used on the internet.
Tor is a free encryption tool and has the capability to provide online anonymity
as well as censorship resistance. Internal traffic is directed through a free
network which consists of more than five thousand relays so that the user’s
actual location can be hidden. It is difficult to track the Internet activities
like visiting web sites and instant messages; the most important goal of this
tool is to ensure the personal privacy of the users.
It is an open source tool for the implementation of virtual private network
techniques so that secured site-to-site or point-to-point connections using
routers or bridges are possible, also remote access is possible. OpenVPN offers
the users a secured authentication process by using secret keys which are
pre-shared.
Stunnel is a multi-platform open source tool which is used to ensure that
both the clients and the servers get secured encrypted connections. This
encryption software can operate on a number of operating system platforms like
Windows as well as all operating systems which are UNIX like. Stunnel depends
upon a distinct library like SSLeay or OpenSSL to implement the protocols (SSL
or TLS)
KeePass is an open source as well as free password management tool for the
Microsoft Windows as well as unofficial ports for operating systems such as
iOS, Linux, Android, Mac OS X and Windows Phone. All the usernames, passwords
and all other fields are stored by KeePass in a secured encrypted database.
This database in turn is protected by a single password.
